To me, the two terms are not synonymous.

However, I can say that alleviating negative energy tends to allow yourself to feel more free or lightweight, as any negative burden can easily weight you down.

Looking back, I did some research and never realized the amount of influence that Zoroastrian teachings carried in Abrahamic as well as non-Abrahamic branches had.

Yeah I think the best place to look for where the original definition as I have in mind comes from is to look at Zoroastrian teachings on duality.
